Sigma Might Make An Important Canon RF Mount Related Announcement Soon

Canon Rf Mount

Sigma might be set to soon announce something important about Canon RF mount lenses (i.e. for the Canon EOS R system).

A new rumor suggests, coming from various sources, that Sigma will soon announce their long term plans concerning RF mount lenses. Moreover, it seems that the development and upcoming release of the Canon EOS R5 might have sped up Sigma’s plans to have RF mount lenses available by 2021.

The interesting part in the rumor is that Sigma will not convert existing ART lineup lenses to the RF mount but come up with an exclusive RF mount lens lineup. And that, in our opinion, is very interesting.

Let’s hope Sigma really comes up with an exciting RF mount lens lineup but we recommend you take this rumor with a grain of salt for the time being.

More RF mount information is listed here.

More to come, stay tuned.

Yet Another Mention Sigma Is Going To Reveal RF Mount Plans Soon

Sigma Canon Eos R Art Prime Rf Mount

We already knew Sigma would make RF lenses. Now another mention surfaced over the web.

We were told Sigma would make lenses for the EOS R back in July 2019. Our source told us Sigma would announce these lenses after they released a bunch of lenses for Sony MILCs.

Latest rumor about Sigma’s RF mount plans has it the company will reveal these plans early 2020. This too fits with our previous rumor. Guess sometimes the Internet silently recycles rumors.

Besides all rumors, you shouldn’t have any doubt that Sigma will jump on the RF mount bandwagon. It’s just plain logic. And that’s great news for all EOS R shooters since Sigma’s recent lenses are nothing less than outstanding.

Sigma Might Release Four Lenses For The Canon EOS R (tell us which one you’d like to see first)

Sigma Canon Eos R Art Prime Rf Mount

Good news for Canon EOS R fans.

In a few weeks Sigma will for the first time announce lenses designed specifically for the Sony Full Frame Mirrorless system. These:

  • 35mm f/1.2
  • 45mm f/2.8
  • 12-24mm f/2.8
  • 24-70mm f/2.8

That’s not the entire story. We have been told (thanks) that Sigma will release these lenses also natively for the Canon EOS R full frame mirrorless system. The source couldn’t tell a timeframe for the RF mount versions. All we know is that they will be released “sometimes later” (i.e. after the release of the Sony versions).

That’s really good news. Sigma makes outstanding lenses and releasing those lenses for the EOS R system will be a great contribution to its lens ecosystem.

One of the oldest and most reliable rumor sites out there, Sony Alpha Rumors, got a hint from a reader that a Lithuanian store has the upcoming Sigma 105mm f/1.4 DG HSM Art lens with a price tag of $1,999.

Hard to say if the price in US$ shown in an online store in Lithuania is the same price Sigma will ask in the USA. B&H Photo and Adorama still have the Sigma 105mm f/1.4 DG HSM Art listed without any price tag. However, $1,999 may turn out to be a pretty realistic price (prediction).

It shouldn’t take much longer until the new Sigma 105mm f/1.4 DG ART HSM lens will be available. B&H Photo has you notified when pre-orders are available.
